Three robbers viciously attack female employee in a jewellery raid

CCTV footage from a jewellers in Green Lanes, north London, shows a man (top left) entering the shop and pretending to have a ring he wanted valued. The camera captures him darting around and putting a black glove on one of his hands before he turns back and jumps over the counter to attack the lone female employee. Shocking video footage shows her trying to run away until her attacker grabs her, puts her in a headlock and drags her to the floor. Two other men (also left) then enter the shop and frantically ransack the shop before trying to escape - only to find they can't open the door. Failing to spot the switch needed to get out, they have to kick it open before fleeing the scene.
